Molar mass and solution conformation of branched alpha(1 - 4), alpha(1 - 6) Glucans. Part I: Glycogens in water [PDF]

open access: yes, 2008
Solution molar masses and conformations of glycogens from different sources (rabbit, oyster, mussel and bovine) were analysed using sedimentation velocity in the analytical ultracentrifuge, size-exclusion chromatography coupled to multi-angle laser light

The Thermal degradation of Bisphenol A Polycarbonate in Air [PDF]

open access: yes, 2005
The thermal degradation of polycarbonate in air was studied as a function of mass loss using TGA/FTIR, GC/MS and LC/MS. In the main degradation region, 480–560 °C, the assigned structures of smaller molecules and linear molecules that evolved in air were

Warum sind Enzyme Makromoleküle?

open access: yesCHIMIA, 1983
The paper is devoted to the question wheter the macromolecular structure is really essential for the chemical and biological qualities of enzymes. Recognizing that high molecular weight compounds are relevant both in nature and in modern technology, the

Structure-functional activity relationship of β-glucans from the perspective of immunomodulation : a mini-review [PDF]

open access: yes, 2020
β-Glucans are a heterogeneous group of glucose polymers with a common structure comprising a main chain of β-(1,3) and/or β-(1,4)-glucopyranosyl units, along with side chains with various branches and lengths.

Influence of polymerisation conditions on the properties of polymer/clay nanocomposite hydrogels [PDF]

open access: yes, 2013
Free-radical polymerisation of acrylamide derivatives in the presence of exfoliated clay platelets has recently emerged as a new technique for the synthesis of strong and tough nanocomposite hydrogels (NCHs) with a unique hybrid organic/inorganic network

Star polymers rupture induced by constant forces [PDF]

open access: yes, 2014
In this work, we study the breakage process of an unknotted three-arm star-shaped polymer when it is pulled from its free ends by a constant force. The star polymer configuration is described through an array of monomers coupled by anharmonic bonds ...

Influence of pH on mechanical relaxations in high solids lm-pectin preparations [PDF]

open access: yes, 2015
The influence of pH on the mechanical relaxation of LM-pectin in the presence of co-solute has been investigated by means of differential scanning calorimetry, ζ-potential measurements and small deformation dynamic oscillation in shear.
